This invention has forits'object to provide means for spotting or applying adhesive on the inner bars of a stack of bars to prevent their becoming loose and dropping out of the package. t t r Further objectsof the invention'will appear from the following specification taken in connection with the drawings which form a part of this application, and in which 7 Fig. lis aside elevation of a machine constructed in accordance with the invention;

The invention may be briefly described as follows. The wrapped articles, such as bars of soap, are fed one at a time to clamps which are mounted on a rotating carrier, the carrier having at properly spaced intervals on the periphery thereof, adhesive applying means which engages the side surface of certain of the articles to be assembled into a stack. The adhesive is applied to the said surface of certain of the articles before the articles are clamped and fed around the periphery of the machine. It is obvious that adhesive is not applied to the inner-surfaces of the outer article of the stack. in other words, if the stack consists of four articles, three of the articles will have adhesive applied thereto, thus securing them together prior to and after banding.

' Fromthe rotary machine carrying the clamps, the articles are discharged to a table and are pressed to- 2,982,065 7 Patented May 2, 1961- frame 10 and the adhesive applying mechanism is shown particularly in Fig. l and will be'first described.

This mechanism consistsof -a pair of parallel disks or plates 11 and 12, which are mounted on a shaft 13 having secured thereto a gear 14 driven by achain 15 r from any suitable source of power. 1 I

The disks 11 and 12 are mounted in spaced relation and each disk has pivotally mounted thereon, as shown at 20, a plurality of clamps 2.1, between which the articles, such as the cakes or bars, are clamped.

Each clamp 21 has a post 25 having a bifurcated yoke 26 in which is mounted a roller 27. Furthermore, each clamp 21 has secured thereto, as shown at 30, a tension spring 31, the other end of the spring being secured to the disk 11 or 12. Thus the spring 31 tends to move the clamp inwardly into operative position to clamp the cake or bar therebetween.

Each clamp or clamping jaw also has secured thereto a post 32 having an adjustable stop 33 and an end 34 which extends through an opening 35 in the disk ll or 12. The clamp is thus guided and limited in its movement. a

In order to control the inner and outer movement of the clamp or clamping jaws 21, a cam 40, suitably designed, is positioned in the path of movement of the rollers 27 and thus causes the clamps to engage and clamp the articles fed along a platform 41 and, further, causes the clamps to release the articles when they are disposed in a position from the position at the platform 41 or as indicated at 42 in Fig. l.

In order to apply adhesive to the inner surfaces of the bars A, B and C in the stack of four bars, as shown in Fig. 7, adhesive applying pads 50 are mounted between the disks 11 and 12 and as the disks are rotated around the axis of the shaft 13 the pads contact the adhesive roller 51 which picks up adhesive from the vat 52. It will be noted that the adhesive applying pads are equally spaced in groups of three and that afterthe third pad, in the direction of rotation of the disks, one pad is omitted before the next group of three appear.

The articles, such as bars of soap, whichhave been previously wrapped, are fed along the platform 41 and the end article X in Fig. 1 has received adhesive when the pad 50A has contacted it before the article X has been picked up by the clampsand fed with the disks. Moreover, the article Y has also received adhesive from the pad 50B. The next article Z will receive adhesive from the pad 50C but the article after the article Z will not receive any adhesive since the position indicated at D in Fig. 1 has no adhesive pad located thereat.

After the articles have received adhesive as above described and have moved from the position at the platform 41 or at the right in Fig. 1 to the position indicated at 412, or through 180 of movement, the articles are discharged by a bifurcated pusher arm 55, which extends at right angles to an arm 56 pivoted to arms 57 and 58 mounted on fixed pivots 59 and 60. The arm 57 has pivoted thereto a link or pitman 61 having a bifurcated end 62 which straddles a shaft 63 on which is mounted a cam 64. The end 62 of the pitman has a roller 65 engaged by the cam and the cam opcrates to reciprocate the link or pitman 61, thus actu ating the arm 55 and removing the articles from be- 3 tween the clamping jaws 21, 21. It will be understood that the jaws are so controlled by the cam 40 that they will release the articles when they are disposed in the position shown at 42.

The articles thus discharged are. moved to a table or support 70 and are held on the support by a spring pressed plate 71. The articles thus moved to the support will move successively along the support in the direction of the arrow shown in Fig. 6.

Assuming that the articles are to be assembled in groups of four, the group of four at the end of the table which has moved against a stop 72 will be moved laterally in the manner shown in Figs. and 6. From the showing in Figs. 1, 5 and 6,, it will be noted that a pair of conveyors or chains 80 and 81 are mounted on a spindle 82 supported in bearings .83 and 84 and uprights 85 and 85, the chains and shaft being disposed above the table 70 and above the group of four articles limited in their movement by the stop 72;.

The chains 80 ,and 81 have mounted thereon. a 'plurality of pivoted pusher plates 90 which have extending at right angles thereto bars 91 on the outer end of which are mounted rollers 92. The, rollers engage a stationary cam surface 93 and move the plates into discharging position as shown in Fig. 5.

The plates 90 are sufiiciently wide to engage the group of articles to be discharged or moved at right angles, and Fig. 6 shows diagrammatically how the articles are moved along an extension or a second supporting table 94. After the group at the right has been moved against a stop 95 it is engaged by a pusher 96 and moved from the platform 94 to a discharge platform 100. Between the platforms 94 and 100 a banding strip ltll is fed by rollers 102 and is cut by a knife 113. This strip is engaged by the group of assembled articles and the band is folded around the advanced end and upper and lower sides of the assembled articles to the position shown in 101A in Fig. 7. The band 101 is provided with suitable adhesive or heat sealing material, which is efiectively secured to the outer surfaces of the articles between sealing plates 103 and 104.

In order to effectively illustrate the adhesive spotted on the faces of the bars or cakes, the adhesive is shown in exaggerated form in Fig. 7 at 110, 111 and 112. Fig. 8 shows the banded articles and because of the adhesive spotted on the faces of the articles at 110, 111 and 112 the inner articles will not drop out of the stack of the banded articles.
